The American Automobile Association (AAA) estimates that 95% of people will travel by car during the 5-day holiday from November 25 to November 29, a decrease of 5 million compared to last year.

He said the US is in a `very, very difficult situation at every level` with a sharp increase in the number of infections and crowded queues of passengers at airports that worry him more than the risk of nCoV infection.

`You come to a crowded airport, line up, no one wears a mask. That puts you at risk, causing us many difficulties,` he said.

Fauci also warned of the risk of contracting the virus from `seemingly harmless encounters` indoors with family and friends during the holidays.

Limiting the number of customers at restaurants and avoiding or closing bars can also `flatten the curve`.

`If you are willing to comply, we can get out of this situation,` he said.

President Donald Trump seemed to admit that Covid-19 was `raging`, contrary to his previous statements during the campaign that the virus would simply `disappear`.

`Fake news media says nothing about the reality that Covid-19 is raging around the world, not just in the US,` he wrote on Twitter on November 21.

Moncef Slaoui, chief advisor to the White House’s Covid-19 vaccine development campaign `Operation Lightning`, said on November 22 that if the first vaccine is approved for use next month, Americans will begin to receive it.

Mr. Fauci also expressed optimism about the possibility of success of Covid-19 vaccines.
